Abstract
A resistive voltage divider includes a first resistor and a second resistor electrically connected in series. Each of the resistors is made of an electrically resistive film material and applied in the form of a trace onto an insulating substrate. The divider's voltage ratio has a value between one hundred and one million, where two ends of the trace of the second resistor overlap at least in part with a first and a second) contacting terminal, respectively, and two ends of the trace of the first resistor overlap at least in part with the first and third contacting terminal, respectively. In order to decrease the parasitic capacitance between the first contacting terminal and the third contacting terminal, the second contacting terminal is placed with at least a screening part between the first and the third contacting terminals.
